NAME

       PDL::RandVar::Histogram -- Arbitary distribution random variables

VERSION

	 Current version is 1.0

SYNOPSIS

	 use PDL::RandVar::Histogram
	 $m = new PDL::RandVar::Histogram($dist);

DESCRIPTION

       Histogram random variables are useful for generating distributions to match arbitrary vector (N-D) data.  On initialization, you feed in a
       clumped array whose value is proportional to the probability of landing in each bin.   You get back values of indices into the original
       vector.	If you ask for it, you can get subsampling in the mantissa of each index.

NAME

       PDL::Exporter - PDL export control

DESCRIPTION

       Implements the standard conventions for import of PDL modules in to the namespace

       Hopefully will be extended to allow fine control of which namespace is used.

SYNOPSIS

       use PDL::Exporter;

	use PDL::MyModule;	 # Import default function list ':Func'
	use PDL::MyModule '';	 # Import nothing (OO)
	use PDL::MyModule '...'; # Same behaviour as Exporter

DESCRIPTION

       "PDL::Exporter" is a drop-in replacement for the Exporter module. It confers the standard PDL export conventions to your module.  Usage is
       fairly straightforward and best illustrated by an example. The following shows typical usage near the top of a simple PDL module:

	  package PDL::MyMod;

	  use strict;
	  use vars qw($VERSION @ISA @EXPORT @EXPORT_OK %EXPORT_TAGS);

	  require PDL::Exporter;

	  @ISA = qw(PDL::Exporter);
	  @EXPORT_OK = qw(inc myfunc); # these will be exported by default
	  %EXPORT_TAGS = (Func=>[@EXPORT_OK],
			  Internal => [qw/internfunc1 internfunc2/],
			 );

	   # ... body of your module

	  1; # end of simple module
